Class JSONStringer

JSONStringer provides a quick and convenient way of producing JSON text.
The texts produced strictly conform to JSON syntax rules. No whitespace is
added, so the results are ready for transmission or storage. Each instance of
JSONStringer can produce one JSON text.

A JSONStringer instance provides a value method for appending
values to the
text, and a key
method for adding keys before values in objects. There are array
and endArray methods that make and bound array values, and
object and endObject methods which make and bound
object values. All of these methods return the JSONWriter instance,
permitting cascade style. For example,

JSONStringer

toString

Return the JSON text. This method is used to obtain the product of the
JSONStringer instance. It will return null if there was a
problem in the construction of the JSON text (such as the calls to
array were not properly balanced with calls to
endArray).
